EDR ratings?

Hi all,

I'm looking for EDR ratings that don't appear to be in Dan's book on the subject. They are:

Only visible name is "KORAN." It's a three column rad similar to the J.C. Mott "Roman," except the dimensions are a bit different. These measure about 37 1/2" tall and about 9 1/2" deep.

"Union Art" five tube radiator made by Union Radiator Co. End plugs have "URCO" engraved in them- nice. These are 34" tall and 9" deep.

Anyone have edr ratings per section for these?

Thanks,

Patrick

    My guess would be

    5.0 EDR per section for nearly any 3-tube column at 38 inches high more or less. Within ten percent and probably right at 5.0 if you ever find a catalog for it.  For the shorter one, I would think 4.5 would be conservatively low, but roughly proportional to the height.



    Check out comparable selections in the EDR book and see if you find a departure from the 5.0 EDR number.

    The Union Art radiator

    would still be 5 square feet EDR at that height. It's one of two that I know of which were less than 38-inch height but still maintained the same EDR. The other was the National Aero. Union became part of National Radiator Corp in 1928 or so.



    The Koran rad is a standard 3-column unit, so it would also be 5 square feet per section.
